I've created an excel file including points of the top250 WTA Ranking players (plus Kim Clijsters and Martina Hingis) as of before the Australian Open and divided them into surfaces. I've chosen not to divide between Hard Court and Carpet, but divide all Hard-Court and Carpet points into indoor and outdoor as it's too difficult to make a distinction between hard court and carpet due to contradictory information given by some tournaments.

The whole amount of points is not necessary the WTA Ranking points as not all points do actually count for the entry ranking.
